Holding device for hot air pipes of a Deokens radiation heater "^

The invention relates to a holding device for hot air pipes a ceiling heating with a reflector plate enclosing the hot air pipes at the top and at the side, the upper part of which is covered with a thermal insulation layer.

Such a heater is known (DE-PS 1 454 390) in which the pipes of each group are in direct contact with one another and the thermal insulation layer is in direct contact with the heating pipes. The individual tubes are suspended in U-shaped beams, which in turn are held in cross rails. The arrangement under the ceiling is then carried out on these cross rails. The laterally sloping downwardly sloping reflector plates provided in this construction are attached to the supports. This bek a might ceiling heater has the substantial manufacturing and assembling technical disadvantage that it is necessary for each pipe a separate holder can be provided which is dariiber constructed also such that are provided at joints of the composite hot air pipes on both sides of the joint one each such bracket got to. It is also disadvantageous that the lateral reflector plates have to be specially attached to the brackets, for example by riveting, screwing, welding or the like. Another disadvantage is that the thermal insulation layer, which is usually present in continuous insulating strips, is placed directly on the pipes

rests, which also, there is a risk of trickling and also the risk of a poor overlap, which Heat losses can occur. Furthermore, the direct current principle is used in this previously known construction applied, which brings an unsound heat distribution *

In another known ceiling heating system (FB-rß 1 120 095), the thermal insulation layer is also immediately placed on the drill and this unit then covered by a reflector that has a horizontal section with laterally sloping downwardly inclined sheets. Lugs are attached to each individual pipe, which go through the insulation and the reflector plate and secured to the reflector plate with the help of cross braces are. It is particularly disadvantageous that there are many suspension points, which among other things the alignment of the pipes involves considerable effort in terms of assembly. The possibility of a height adjustment is not provided for here at all. A special design of the butt joint is in this known embodiment not provided, this configuration in particular contributing significantly to simplifying assembly. Disadvantageous is also that the arrangement of the insulation, the reflector effect is unfavorable and there is also a risk of Eiesel. In addition, this construction does not take into account the thermal expansions that occur in such systems.

A heater is also known / with the reflector plate and the thermal insulation layer form a unitary mounting element by arranging the thermal insulation layer in chambers which correspond to the shape of the reflector plates. The individual heating pipes are also on the inner reflector plate hung with the help of U-shaped beams. To the

The order of these assembly elements serve uprights, those of your belts on special suspension devices or support brackets being held. This construction brings a considerable amount of material and Montage expenditure, with complicated Suspensions, which also have an unfavorable effect on the heat distribution, are provided. Special Measures to absorb temperature expansion are not provided.

The invention is based on the object »a Leoken radiation heater of the type mentioned in such a way that, while maintaining optimal thermal values, a considerable Assembly simplification is achieved.

This object is achieved according to the invention in that the holding device has a U-shaped bligel the plug-in pipes are attached, can be pushed over the hot air pipe ends, one of two side parts and the Heat-absorbing cover part made up of sheet metal reflector part on which the Bligel is attached.

An advantageous embodiment is that the Plug-in pipes are attached to the bracket by means of a bolt which is fastened to the inside of the reinforced plug-in pipe Nut is screwed in.

It is advantageous to proceed in such a way that the plug-in pipes are arranged next to one another and have different lengths.

It is advantageous that the plug-in tubes are connected to one another by spacers.

Finally, according to a further advantageous proposal, the procedure is that the side parts of the reflector sheet metal part

* η their lower edge bent in a U-shape and attached to the U-veneered bracket below , so that the side parts on the upper side have an inwardly bent leg, resiliently resting on the bracket, on which a'weiterer near and above standing leg adjoins, and that the heat-insulating cover is clipped onto the upstanding legs from above.

The ceiling heating according to the invention brings the significant advantage that the parts of the heater at the Eineatzort by simply plugging together to form a unit can be connected, with height and escape regulation through the directly attached adjustment units is made much easier. The individual parts can also be transported to the site to save space, because the reflector consists of three metal sheets, which are attached to the Einsa-czort can be combined with the carrier to form a stable reflector. The upper horizontal one is used here Reflector sheet for secure mounting of the thermal insulation layer, whereby the risk of trickling is also avoided. Overall, the connecting element is at the joints of the individual Tube elements at the same time support and fastening element of the tubes, the panels, as well as the reflector and the thermal insulation layer. Furthermore, there is the advantage that the spacing of the radiant tubes means that no heat unu Transmission of sound occurs through touch.

The invention is explained in more detail in the following description with reference to the exemplary embodiments shown in the drawings.
